According to some owners here in the US, Redline 5W50 showed up as really good alternative to 10W60. Redline 5W50 could have HTHS very close to TWS 10W60.Thanks for the information! Interesting to read the opposite view.
As for rod bearings on N55 first issue is known fact: people do not prime oil pump after OFHG change.
Second is that there are suddenly numerous N55 engines with rod bearings failure. But why now? I mean engine is in use since 2010. I think it is since they moved to that LL01FE garbage.
